Medium Medium refers to the substance that carries heat through the heating system. Systems are either designed to use either Hot Water or Steam as a medium, and components are usually specific to one or the other.

Hot Water

Fuel Type To create heat, some form of fuel is required. Fuel Type specifies what the product uses as an input to create heat.

Natural Gas

Combustion Type

Condensing

Vent Type Products that use combustion (burning) of fuel to create heat also create potentially dangerous gasses that need to be exhausted (AKA "Vented"). Depending on the product, venting can be done via a chimney, through a side wall, or use a second vent to provide fresh air to the appliance.

Direct Vent

DHW Production DHW (Domestic Hot Water) is potable water for uses other than space heat. Some boilers are able to provide DHW "out of the box", while others can do so with the purchase of optional accessories.

Modulating/Staging Stages are unique speeds or levels that equipment can operate at. More stages allow for better fine-tuned control of output, which improves comfort and efficiency. Modulating equipment can operate across a range of levels, giving the highest level of fine-tuned control. Learn More

Performance

Maximum Input Capacity The Maximum Input Capacity describes how quickly the appliance will use fuel when delivering it's maximum capacity. The units may change depending on the fuel being used.

299000 BTU

Minimum Input Capacity

29900 BTU

DOE Heating Capacity Also referred to as Gross Output, this is the output of a boiler after accounting for combustion efficiency. We recommend sizing hot water boilers based on the DOE Heating Capacity.

280000 BTU

Net I=B=R Capacity I=B=R, also referred to as Net Output or AHRI Capacity, is the rated heat output of a boiler after accounting for combustion efficiency, piping loss, and an extra pickup factor. We recommend sizing steam boilers based on the I=B=R rating.

The Evergreen line combines over a century of Weil-McLain's heating experience with the latest in boiler technology. With a 95% AFUE efficiency rating, the EVG 299 will help lower utility bills while keeping your home comfortable from day one. Using its modulating burner to scale fuel use and condensing technology to reuse heat that traditional boilers lose, the EVG 229 is rated as one of the most efficient boilers on the market. The Evergreen also brings a new level accessibility to home heating. With multiple features making the EVG 229 easy to install, use, and maintain, the Evergreen line has made home boiler use easier than ever. The flexibility of the Evergreen line is unmatched, as up to eight units can be connected and controlled simultaneously, and with both wall and floor mount options, the Evergreen boiler can fit in almost any accommodation.

Product Features

Durable DesignUsing their stainless steel heat exchanger technology and non-metallic condensate base, Weil-McLain has designed one of the most durable boilers available. Built in diagonistic tests will make sure your unit is running at peak efficiency at all times.

Simple EfficiencyWith a 95% AFUE efficiency rating, the Evergreen series is one of the most efficient boiler lines on the market. Not only will this keep utility bills lower, but it will help to reduce carbon footprint as well. With an easy to access display, setting up and maintaining high efficiency has never been simpler.

Easy Heat, Effortless ComfortThe Evergreen boilers are easy to install and even easier to maintain. With an optional wall kit, they will fit in nearly any space. A crystal-clear display allows for easy access to all settings, allowing for the optimization of heat flow throughout your home.

The Evergreen boiler isnít available in any size smaller than 220k BTU input. This is because itís designed specifically for higher output applications. Thatís also why it offers built-in support for up to 8 boilers. An array of sensors helps it operate efficiently Ė especially the redundant sensors for supply and outdoor temp. The burners can handle changes in demand with an unusually excellent 10:1 turndown ratio. ZoneStacking allows for up to 24 zone control (with 8 boilers) without... more

The Evergreen boiler isnít available in any size smaller than 220k BTU input. This is because itís designed specifically for higher output applications. Thatís also why it offers built-in support for up to 8 boilers. An array of sensors helps it operate efficiently Ė especially the redundant sensors for supply and outdoor temp. The burners can handle changes in demand with an unusually excellent 10:1 turndown ratio. ZoneStacking allows for up to 24 zone control (with 8 boilers) without additional 3rd party controls. There are also three built-in sequencing options for multi-boiler Ė Series, Parallel, and Smart. Smart sequencing maximizes part-load efficiency by turning on as many boilers as possible.
